Ken Mattingly

That's correct. Okay, now we're going to panel 5: circuit breaker ECS TRANSDUCERs, PRESSURE GROUP 1 and 2, MAIN A and MAIN B. That's four circuit breakers, closed.

Jack Swigert (CMP)

ECS TRANSDUCERs, GROUP 1 and 2, MAIN A and MAIN B, four, to close.

Ken Mattingly

That's correct. Okay, now. Circuit breaker ECS TRANSDUCER, TEMPERATURE, MAIN A and MAIN B, that's two of them, closed.

Jack Swigert (CMP)

CB ECS TRANSDUCER, TEMPERATURE, MAIN A and MAIN B, closed.

Ken Mattingly

That's correct. On panel 4: PRIMARY ECS GLYCOL PUMPS, one, to AC 1.

Jack Swigert (CMP)

Primary ECS GLYCOL PUMPS to 1, AC1.

Ken Mattingly

That's correct. Okay, then we'll finish going back to the tunnel vent, and verify the LM/CM DELTA-P and make sure it's been holding pressure. And we'll come back again and rehash all of the hatch integrity check and tunnel vent procedures with you. The next thing I want to read off is the EI minus 1 plus 20. We'll go to panel 7: BMAG number 1 POWER to WARM UP.

Jack Swigert (CMP)

BMAG number 1 POWER to WARM UP.

Ken Mattingly

That's correct. Then at EI minus 1 plus 10, we'll perform SCS powerup per checklist, page G/2-4.

Jack Swigert (CMP)

Okay. Perform SCS powerup per G&C checklist, page 2-4.

Ken Mattingly

That's correct. Okay, on panel 4: SUIT COMPRESSOR NUMBER 2 to AC1.

Jack Swigert (CMP)

SUIT COMPRESSOR 2 to IC1.

Ken Mattingly

That's correct. SPACECRAFT CONTROL to SCS.

Jack Swigert (CMP)

SPACECRAFT CONTROL to SCS.

Ken Mattingly

Okay. And your MANUAL ATTITUDE switches, as you desire. We're coming up on jettison of the LM, so that's just like separation.

Ken Mattingly

Okay. And we'll do a GDC aline.

Jack Swigert (CMP)

Okay. Perform a GDC aline.

Ken Mattingly

Okay. On panel 8: ROTATION CONTROL POWER, DIRECT, 1 and 2, MAIN A/MAIN B.

Jack Swigert (CMP)

Okay. These are circuit breakers, ROTATION CONTROL POWER, DIRECT, 1 and 2, MAIN A and MAIN B, closed.

Ken Mattingly

Okay, Jack. I was thinking switch. Let me verify that's a circuit breaker, too. I think we have to get both of them.

Jack Swigert (CMP)

Okay, there's those four circuit breakers over there, Ken. When you said panel 8, that's what I thought you were talking about. I don't think the circuit breakers are out right now, but why don't we just put—verify the circuit breakers and put the switches to MAIN A/MAIN B.

Ken Mattingly

Okay, that's correct, Jack. Okay, at EI minus 1 hour, we're going to be doing the LM jettison; so just prior to that, we want to do a P47.

Jack Swigert (CMP)

Okay, say at about 1 minute prior to LM jettison, huh?

Ken Mattingly

Yes, just something that's comfortable for you.

Ken Mattingly

All right, after we've? done that, we want to get panel 8, SEQUENTIAL, PYRO ARM, two of them, ON.

Jack Swigert (CMP)

Okay. I get a GO from MSFN for this?

Ken Mattingly

Okay, John says we can watch it.

Ken Mattingly

All right; the next thing is CSM/LM FINAL SEP, two of them, ON, up.

Jack Swigert (CMP)

CSM/LM FINAL SEP, two, ON.

Ken Mattingly

That's correct. Now we're going back to panel 8, and it's SEQUENTIAL, PYRO ARM, two of them, to SAFE.

Jack Swigert (CMP)

Okay. SEQ PYRO ARM, two, to SAFE.

Ken Mattingly

That's correct, and go back to P00.

Ken Mattingly

All right. And now it's time to configure for single ring.

Jack Swigert (CMP)

Okay. Configure for single ring RCS.

Ken Mattingly

That's right, and since you're still an hour from EI, I guess it wouldn't hurt to use MINIMUM IMPULSE or something like that rather than the DAP, at least not until you get closer down. We'll have the DAP loads for you later.

Ken Mattingly

Okay. And as soon as you've gotten yourself all set up with a good control mode, you want to maneuver to the entry attitude.

Jack Swigert (CMP)

Maneuver to entry attitude per the pad.

Ken Mattingly

That's correct. And we show EI minus 55, which really means when you get to the entry attitude, we have a sextant star check for you. And that will be on the pad.

Jack Swigert (CMP)

Okay. Perform a sextant star check.

Ken Mattingly

Okay. And I want to remind you to park the optics at 90 degrees of shaft.

Jack Swigert (CMP)

Okay. Say again why, Ken. I didn't understand that.
